forms a part of the spindle.- This collar a I To all whom it mayconcern.-

Be it known that I, WALTER G. MORRISON, of Willimantic, in the county ofWindham and State of Connecticut, have invented certain new and usefulImprovements in Spindles, of which the following is a full, clear, andexact description,whcreby any one skilled in the art can make and usethe same.

The object of my invention is to provide a spindle with improved meansfor removably securing it in operative connection with the tubularbolster and oil-cup; and to this end my invention consists in thedetails of the several parts making up the device as a whole and intheir combination, as more particularly hereinafter described, andpointed out in the claims.

Referring to the drawings, Figure 1 is a view in vertical centralsection on the spindle and its connected parts. Fig. 2 is a detail View,in section, through the base of the spindle on the plane passing throughthe-locking-collar. Fig. 3 is a detail plan view of the locking-ring.

In the accompanying drawings the letter a denotes a spindle; b, asleeve-whirl; c, a tubular bolster, within which the spindle isimmediately supported; (1, the oil-cup, and e the locking-ring thatserves as acover to the cup and as a means of regulating the tension ofthe bolstersupporting spring. The upper part (1' of the oil-cup haspreferably a larger diameter than the lower part, a shoulder between thetwo serving a useful purpose in the attachment of the spindle as a wholeto the rail of the spinning-frame. W'ithin the oilcup the spring f islocated with one end th rusting against the shoulder within the cup andthe other end thrusting upward against a projecting collar is on thetubular bolster. The locking-ring e is threaded as a means of securingit in place in a threaded socket in the upper end of the oil-cup, thelower edge of the ring pressing upon the upper surface of the collar isand forcing it down upon the springf. The ring may be used as a means ofadjusting the tension of this spring.

The upper surface of the locking-rin g c has an eccentric opening e, thediameter of which is slightly greater than the diameter of thelocking-collar a, that projects from the outer surface at the lower endof the sleeve that will pass freely through the eccentric opening in thelocking-ring, provided the latter is not secured in the oil-cup, theeccentric arrangement of the opening in the ring compelli g the'lateralmovement of the ring in order to fit the parts together. The parts areassembled With the locking-ring unscrewed from the socket in the oil-cupuntil the collar on the sleeve has been slipped through the opening inthe locking-ring, when the latter is then screwed to place. The resultof this construction is that at all times some portion of thislocking-collar a underlies the top of the locking-ring in such manner asto prevent the vertical lifting of the spindle out of its support in thetubular bearing. It is, in fact, impossible'to remove the spindlewithout unscrewing the ring from the seat in the oil-.

cup. This method of constructing the interengaging parts provides asimple and very efficient means of preventing the accidental removal ofthe spindle from its supportingbearings while the spindle is in use inthe frame. The lower part of the grooved pulley on the sleeve-whirl isprovided with a downturned flange, the whole forming an overhangingcover that closes the upper part of the cup and hangs sufficiently belowthe edge of the cover within it to prevent any spattering of oil withwhich the cup is filled for the purpose of lubricating the bearings. Theoil passes from the cup into the tubular hearing through an opening thatmay be made through the wall of the tubular bolster, near the step,upward along the spindle to the top of the tubular bearing, where itpasses outward and downward through openings that may be made in thecollar and back again into the well, being kept in constant circulationby the rotary movement of the spindle and by the capillary attraction ofthe thin film of oil between the bearing of the spindle and the innerwalls of the tubular bolster.

I claim as my invention 1. In combination with the oil-cup d, a tubularbolster 0, provided with the projecting collar 0, located within thecup, the spring f, located within the cup and underlying the collar onthe bolster, the locking-ring removably secured to the top of theoil-cup and having an eccentric opening, and the spindle a,

having a locking-collar a, a portion of which underlies the locking-rim,all substantially as described.

2. In combination with an oil-cup, a locking-collar having a verticaladjustment detachably secured to said cup and having an eccentricopening therethrough, the spindle having a projecting locking-ringunderlying in part an edge of the opening in the collar, a tubularbolster supported on a spring Within the oil-cup and provided with acollar projecting into the path of movement of the lower edge of thelocking-collar, and the supporting-spring underlying said flange, allsubstantially as described.

3. I11 combination with an oil-cup, a locking-collar detachably securedto said cup and having an eccentric opening therethrough,the spindlehaving a projecting locking-ring underlying in part an edge of theopening and with a downturned flange surrounding said ring the tubularbolster supported within the oil-cup and having a collar, the edges ofwhich are adapted to engage the locking-collar, and the spring havingone end resting upon a projecting part of the cup and with its upper endengaging the under surface of the collar on the bolster, allsubstantially as described.
